Here's an idea for you Celandina: Since most of your traffic will come from Google anyway, it’s worth going straight to the source. Google’s own SEO guide explains exactly how to structure pages and improve rankings:

It’s clear, free, and written for regular site owners. It's not long, and it my opinion, it's good for every website owner to know this.
Cheers!
